1950 Summary
General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
The Hickman, KY – Obion River levee system provides flood risk reduction for portions of southwest Kentucky and northwest Tennessee. The levee system extends south form Hickman, KY to the mouth of the Obion River. The levee system consists of 5 levee segments totaling 62.2 miles of levee. The levee systems prevents flooding from the Mississippi River. The leveed area is bounded to the east by the bluff.
The levee system is part of the Mississippi River and Tributaries (MR&T) project. The MR&T project was authorized by the 1928 Flood Control Act. In the wake of the devastating 1927 flood, it was deemed necessary to put into place a comprehensive, unified system of public works within the lower Mississippi Valley that would provide unprecedented flood risk management and an equally efficient navigation channel. The MR&T project continues to be one of the world’s most comprehensive and successful flood risk reduction projects.
Performance & Condition
General text description of the historical and anticipated performance of the levee, the people and property benefitting from the levee and who may be at risk of flooding, and actions to address areas of concern.
PLEASE NOTE: The following Risk Characterization is a description of risk associated with this levee system. It is currently undergoing review and may be updated in the future.
The Hickman KY - Obion River Levee System has been successful at preventing flooding in the past with considerable flood fighting efforts. Significant investment in the levee has decreased but not eliminated flooding risk. The potential exists for flood events higher then experienced to occur that could lead to overtopping or breach of the levee or floodwall. If that occurred, the areas behind the levee would experience high damages and potential loss of life. Levee sponsors, local communities, and USACE are taking action to reduce risk associated with the levee. However, individual residents and local businesses have roles and responsibilities in reducing their own risk
